alt Hacker NewsYes, the "correct" reaction to the ambiguous tiles is to hover a bit indecisively. You need to waste a certain minimum amount of time on the CAPTCHA. I've found that applying videogame reflexes and zapping all the tiles in a short period of time is a fail, even if they're the correct tiles.
I think it depends on how much it trusts your ip address / user agent. I used to use an extension, nopecha, that would just use ocr and then select all the matching boxes, and it never seemed to get flagged; but I have a lot more trouble on a vpn ip like proton. These days I use buster to solve captchas and it works enough of the time that I don't have to fight with captchas.
